PERMUTATION-PADLOCK.

Specification of Letters Patent.

Application filed March 9, 1918. Serial No. 221,479.

To all whom it may concern:

Be it known that I, CLARENCE E. ANABLE, a citizen of the United States,residing at Sacramento, in the county of Sacramento and State ofCalifornia, have invented certain new and useful Improvements inPermutation-Padlocks, of which the following is a specification.

This invention contemplates the construction of a permutation lock whichmay be manipulated in the dark as well as in the light and one which maybe applied wherever a padlock may be required.

Therefore the invention for which patent protection is sought consistsin the structure of parts and their combination for the purposespecified, substantially as herein set forth and claimed.

In the accompanying drawings, which form a part of this specification,Figure 1 represents the improved lock in the form of a robe lock for usein automobiles, the shackle being divided in approximately equal parts.Fig. 2 is a transverse medial section of said lock on the lin 2.2. Fig.3 is a rear view of the interior of the lock, the back-plate beingremoved and parts broken away and the shackle broken off. Fig. 4.is asection on the line 44, Fig. 2.

In the form of lock selected forillustratconcentric drums 6 and 7 thehalf shackle 8 being integral with drum 6 and the half shackle 9 beingintegral with drum 7 The head 10 of the inner drum 7 is also preferablyintegral therewith, while the outer drum 6 is confined to the inner drumby a removable head 11, secured to the inner drum by screws 12, thesockets for which are seen at 13 in Fig. 3. After the lock has beenassembled the heads of these screws may be filed down to remove thenicks thereby preventing removal of the screws by a screw-driver.

The combination-operating spindle 14 with its milled head 15 is locatedin the common axis of said drums and is journaled for rotary and axialmovement in a stud 17 in the center of the head 10 of drum 7 About saidstud 17 are located concentric permutation rings or tumblers 18 and 19provided with screw pins 20, 21, 22, and 23 by which said rings may bemoved through the agency of a finger 24 projecting from the spindle 14.The ring 19 has a flange formed on it which enters an annular recess inring "bitrarily for 3 right/ 2 left. ing point is taken at the blankspace in the notched disk, it being composed of the re- 18, the latterbeing held to the head-10 by 'Patented'Aug. 12,1919.

a spring 25 confined by the head 11. Said spring therefore holds bothrings to head 10 and restrains ring 18 while ring 19 is beingmoved. 2

The lock is set'for a particular combination by locating the pins 20 23in the de- 7- sired sockets 26 and 27 in the concentric rings. A clickmechanism, through which to work the combination by sound or touch, iscomposedof a notched disk 28,formed on the end of stud 17, and thefinger 24, the

finger being held to the disk'by a spring 29 located about the spindle14 between a shoulder thereon and the head 11. i

i The element by which the parts of the shackle are locked togetherconsists of a bolt 31 located radially in the head 10, Fig. 4,

and formed to engage notches 32 .in the drum 6. 'The inner endof saidbolt is .engaged by a conical portion of the spindle 14 and is forcedthereby into said notches;

The inclined faces of the notches force the 7 bolt inward when thespindle is pulled outward and the shackle opened. The axial movement ofthe spindle therefore controls the locking bolt, and the axial movementof the spindle depends upon the position of the combination rings 18 and19, which are notched to receive the finger 24. These notches orrecesses appear at 33 and 84.

There is also a notch or recess 35 in the ratchet disk 28. When thesethree recesses are brought into alinementby proper rotation of thespindle the finger may enter them on pulling out on the knob 15. Thenthe bolt 31 will slide inas opening force is applied to the dividedshackle.

The drawings show the mechanism in locked position and the combinationset ar- The startcess 35, which obliterated one ridge of the notcheddisk, and the smooth surface at the left (Fig. 3) of said recess, thewidth of another ridge. This blank space, equal to two ridges, is easilyfelt and likewise noted by the ear, when the finger 24 is moved over thedisk on turning the knob 15.

To unlock the lock: Rotate the knob till finger 24 slides into the blankspace, then turn to the right three steps, the spring forcing saidfinger into the successive notches of the disk 28 thereby enabling theoperator to sense each step. Recess 34 is then in line with recess 35.Then reverse till said finger again slides into the blank and continuetwo steps to the left. Recess 33 is theninalinement with 34 and 35. Thenturn back to the blank space, when finger 24 may be drawn into saidalined recesses and the spindle drawn out so that the conical portionthereof will recede from the end of the bolt 31, which will be free toslide inwhen the shackle is opened. The spring 29 tends to keep theparts in unlocked position:

' To apply the lock, the parts of the shackle may be inserted wheredesired or clamped upon'the thing tobe held, then the spindle is pushedin till finger '24: is out of the recesses, when, on twirling theknob'in either direction, said recesseswill be thrown out of alinementby the finger striking the pins in the combination rings. The fingerthen holds the'spindle in and the conical portion thereof has forced thebolt out into one 'of the notches Therefore the drums '6 and 7 will beheld against rotation upon one another and the parts of the shackle willbe maintained in locked position.

Obviously a dial may be used on head 10 for cooperation with knob 15 ifdesired, but the combination isso readily followed by touch and soundthat a visual indicator is not at all necessary.

The invention claimed is:

1. In a permutation lock, the combination of two concentric rotatabledrums, each of said drums carrying a portion of a part to be looked, aradially movable bolt .for locking the drums against rotation, aspindlehaving a rotary and axial movement, said bolt being controlled bythe axial movement of said spindle, means on the spindle for controllingits axial movement, and permutation tumblers within the innermost drumconcentric with each other and having openings adapted, when alined, topermit the passage of the spindle-controlling means.

2. In a permutation lock, the combination of two concentric rotatabledrums, each of said drums carrying a portion of a divided shackle, aradially movable bolt for locking the drums against rotation. anactuating spindle having a rotary and axial movement, means mounted onthe spindle for controlling its axial movement, permutation tumblersconcentric with the drums, said tumblers having openings adapted, whenalined,-to permit the passage of the spindle controlling means, andother means, also mounted on the spindle, for controlling the movementof'the bolt by the axial movement of the spindle.

In a padlock, a divided shackle having the parts thereof pivotedtogether at one end, ah'ol'low stud in the axis of said pivot and havinga recess'in its end, concentric, movable permutation rings mounted aboutsaid stud and each provided with a radial opening, an actuating spindlejournaled in said'stud and axially movable, a finger extending laterallyfrom said spindle for moving said rings and adapted to enter theopenings in the rings and in the stud when brought into alinement, andmeans projecting into the path of movement of the spindle and controlledby the axial movement thereof for locking the parts of the shackletogether. r

Ina padlock, a dividedshackle having the parts thereof pivoted togetheratone end, a hollow stud in the axis of the pivot and having a ratchetdisk on its end and a recess therein, concentric,-movable, permutationrings mounted about saidstud and each provided with a radial opening andwith changeable operating pins, an actuating spindle'provided with aconical portion and journaled in said stud and axially movable, a fingerextendinglaterally' from said spindle for engaging said pins and adaptedto enter the openings in the rings and in the stud when brought intoalinement, and a radially reciprocating bolt for locking the parts oftheshackle engaged by said conical portion of the spindle when thespindle is axially moved.-

In testimony whereof I afiix my signature.
